Cardanol extracted from cashew nut shell liquid is a well known material for antibacterial activity. In fact, cardanol exhibited excellent antibacterial property when it used as side chain attached to the polymer backbone. However, the antibacterial mechanism of cardanol is still obscure. To investigate the effect of long alkyl chain moiety in the cardanol, phenol with various lengths of alkyl chain (C6, C8, C10, C12, C16) was synthesized via Williamson ether synthesis, which is further reacted with glycidyl methacrylate for introduction of acylate backbone. Polymers having silliar structure with cardanol was synthesized and characterized by NMR,IR, GPC and TGA. Also, the antibacterial activity was confirmed by colony counting method and polymer having C12 alkyl chain showed the highest activity with 99.9% killing rate. |
